The NOAA ENCs are in S-57, a data standard developed by the International Hydrographic Organization (IHO) to be used for the exchange of digital hydrographic data. Nautical chart features contained within an NOAA ENC provide a detailed representation of the U.S. coastal and marine environment. This data includes coastal topography, bathymetry, landmarks, geographic place names and marine boundaries.For each ENC there is information that includes the tags <name>, <lname> (title), <src_chart> (equivalent raster chart number), <cscale> (equivalent raster chart scale), <coast_guard_districts> and <states>. Each ENC dataset is available for download as a .ZIP file. The <zipfile_location> tag includes the URL of download location, and the <zipfile_datetime> tag includes the date and time that the .ZIP file was created. ENCs have edition numbers and dates. The <edtn> tag is the Edition Number, the <updn> tag is the Update Number, the <uadt> tag is the Update Application date and the <isdt> tag is the Issue Date. The Update Application Date is the date that a Base Cell (000 file extension) is created. The Issue Date is the date that an Update Patch (001, 002, etc., file extension) is created. Other information for each ENC includes the <nm_agency> tag which designates either the National Geospatial-Intelligence Agency (NGA) or U.S. Coast Guard, and the tags <doc> and <date> which represent the latest published document through which the ENC is cleared. The <cov> tag includes information describing the geographic coverage of the ENC.completedNational Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Office of Coast Survey (OCS)http://ocsdata.ncd.noaa.gov/idrs/inquiry.aspxNOAA's Nautical Inquiry Webpageownercontinualdatasetnm update agency: NGA; doc: 1118; date: 2018-03-17lnm update agency: USCG05; doc: 1018; date: 2018-03-06coast guard district: 5state: VAregion: 4vector20000engoceanspanel number: 1; type: E37.02354 -76.0997236.9085 -76.0997236.9085 -76.1593936.95292 -76.1593936.95292 -76.1935636.9085 -76.1935636.9085 -76.2404437.02722 -76.2404437.02722 -76.3263337.0274 -76.3263337.0274 -76.0997237.02354 -76.09972S57 - IHO Transfer Standard for Digital Hydrographic Data3.1ENC - Electronic Navigational Chart Product Specificationdataset0.205378532409668http://www.charts.noaa.gov/ENCs/US5VA20M.zipzipfile date and time: 2017-12-18T13:17:28ZdatasetNOAA paper chart12256
